X = - 6 and y = 1. By using substitution, you simply plug y into x = - 2y - 4. So, it would look like this x = - 2 (x + 7) - 4. Then you distribute to find x. After finding x, you plug it into y = x + 7.

Which of the following choices is the solution to this system of equations? x = - 2y - 4y = x + 7
